Notes:
This research is to investigate the dynamic characteristics of the grinding process. A kind ofrobust grinding wheel reciprocating arrangement is schemed out, which realizes the precisepoint-grinding machining. The grinding wheel reciprocating movement is driven by a linear motor toreplace the traditional crank or hydraulic pressure drive device. Based on the time series method, themodal experimental analysis technique has been adopted in this paper. By acquiring accelerationsignals of multiple positions of the grinding wheel slide, the dynamic characteristics are analyzed andthe modal parameters of the structure are identified by virtual analysis program. The boundarycondition of the finite element model is adjusted for optimizing its dynamic characteristic. Theequivalent substructure is created and modified in order to improve the surface grinding quality. Thisstudy has got satisfying results. The grinding wheel movement realizes the self-regulation control andreduces the surface waviness and roughness during high speed point-grinding operation
